METALLIC FASTENER.

SPECIFICATION forming part of Letters Patent No. 512,621, dated January 9, 1894.

Application filed July 27,1893- Serial No. 481,646. (No model.)

To all whom it may concern:

I 3e it known that I, GEORGE W. MOGILL, a cltlzen of the United States, residing at New York, (R1verdale,) in the-county of New York and State of New York, have inventednew and useful Improvements in Metallic Fasteners, of which the following is a specification.

Thls invention relates to that type of metal- 110 fasteners having duplex-pronged shanks and a capped head piece.

The objects of my invention are to provide a new and improved metallic fastener particularly designed for basket and paper box fasten1ng,decorating and protecting the leather in harness, belts, dog collars, for upholstery fastenings, buttons, knobs for protecting the corners of books, and satchels, and many other and similar purposes; to provide a novel ornamental head which is light, strong, durable, and desirable and presents a distinguishing and characteristic appearance to the eye; to prov de such a construction that a cap varymg in shape or contour may be able to be fully closed on all sides, except the small po1nt in its bottom wall or base, through which the duplex-pronged shank extends; to pro: v1de such a novel construction and arrange: ment of cap and duplex-pronged shank that the head of the shank conforms to and corresponds in contour with the interior of the cap and braces and sustains the latter; and to provide a novel hollow capped fastener, light in weight, and having a duplex-pronged shank so shaped as to form a contracted neck in uxtaposition to the cap with separated prongs to pass through the articles to which the fastener is applied.

To accomplish all these objects my invention consists in the features of construction and the combination or arrangement of parts hereinafter described and claimed, reference being made to the accompanying drawings, 1n which-= Figure 1 is a detail side elevation of the duplex-pronged shank. Fig. 2 is a sectional side elevation of a metallic fastener constructed in accordance with my invention.

I In order to enable those skilled in the art to make and use my invention, Iwill now describe the same in detail, referringto the The circular or ring portion 3 of the duplex shank is slightly curved in cross section, as represented in Fig. 21, for the purpose of imparting an arched form to the circular head or ring, so that it will accurately conform to and fit the internal surface of a ball-shaped cap 4, Figs. 2, 3, and 4, formed of a single piece of sheet metal which is applied to the circular or head portion 3 and shaped into the form of a hollow ball or sphere which is entirely closed on all sides except the single small point or slot 5 through which the duplex-pronged shank extends.

The metallic fastener constructedas described is particularly designed for basket and light box fastening, decorating and protecting harness, belts, dog collars, for upholstery fastenings, buttons, and knobs for protecting the corners of books and Satchels, but is useful for many other purposes not necessary to enumerate.

The device is applied by forcing the two prongs or members 1 and 2 through the article, object, or material, and flattening them down thereupon in opposite directions, whereby the article, object, or material will be provided with a button, ball-shaped, or hollow spherical ornamentation which presents a characteristic and distinguished appearance and which is completely closed on all sides, so that no joint or opening is visible.

The duplex-pronged shank may be formed as shown in Fig. 5, where the two prongs or members 1 and 2 are spread apart and are joined to the circular or ring head through the medium of a contracted neck 6.

The duplex-pronged shank Fig. 5 is provided with a hollow ball shaped or spherical head or cap 4, Fig. 6, constructed in all respects the same as described with reference to Figs. 2, 3, and 4.

In Fig. 7 the head 7 of the duplex-pronged,

shank is elongated and flattened as compared with the circular or ring shape, Figs. 1 and 5, and in this form of shank a hollow metallic head, or cap 8, Figs. 8, 9, and 10, is employed, which head or cap is fully closed on all sides except the small point or slot 9 through which the duplex-pronged shank extends.

In Fig. 11 the duplex-pronged shank is constructed with a head 10 similar to that exhibited by Fig. 7, and with a contracted neck 12 similar to that shown with reference to Fig. 6, but this neck is strengthened, and its two parts held together through the medium of a collar 13.

In Fig. 12 the head or cap 14 of the fastener is constructed the same as described with reference to Figs. 8, 9, and 10, but the duplex-pronged shank is provided with a contracted neck 15, and the extremities of the prongs or members 1 and 2 are separated or The construction exhibited by Fig. 15 is the same as that exhibited by Fig. 14, exceptthat the duplex-pronged shank is formed with a contracted neck 20, and the two prongs or members 1 and 2 are separated or spread apart.

In Fig. 16 the head portion 21 of the duplexpronged shank is substantially triangular in shape, and with this form of head a hollow conical head or cap 22, Figs. 17, 18, and 201s employed.

The construction shown in Fig. 20 is the same as that shown in Figs. 17 and 18, except that theduplex-pronged shank is formed with a contracted neck 23, and the prongs or members 1 and 2 are separated or spread apart.

In the modification Fig. 19, the head portion 24 of the duplex-pronged shank is substantially triangular, as described with refererence to Fig. 16, and the two prongs or members 1 and 2 are separated or spread apart while a contracted neck 25 of tubular form, Fig. 19, is employed, which tubular neck is constructed by shaping each part of the metal composing the neck into semi-circular form in a transverse direction.

In all the constructions described and shown the duplex-pronged shank 1s formed with an enlarged head portion of loop form, which may be circular, oblong, triangular, or of any other suitable configuration, and the metallic head or cap is composed of a single piece of sheet metal correspondingly shaped throughout the vertical diameter, and so applied that it forms a hollow cap piece which is fully closed at every point, and on all sldes, except the single small point or slot through which the two prongs or members of the duplex-pronged shank extends.

The improved construction provides anovel, simple, strong, durable, and efficient duplex-pronged shank having a llght hollow head or cap piece, which is fully closed on all sides, and consequently is without v1s1ble joint or openings to render it objectionable in appearance when applied as desired.

The device is suitable for many purposes, but, as before stated, is more particularly designed for application as light decorative fastenings for basket work, light paper, and wooden boxes; for decorating and protecting the leather in harness, belts, dog collars, &c.; as knobs for protecting the bottoms of satchels and corners of books; in the upholstery of furniture; as buttons; and thousands of other uses where light ornamental binding is required.

Having thus described my invention, what I claim is- 1. As an improved article of manufacture, a duplex-pronged fastener,- consisting of two prongs or members having an open loopshaped head, and a hollow cap correspondingly shaped and elongated through its vertical axis applied to the loop-head, and fully closed on all sides and under thelooped shaped 512,621 r A r 3 head except the single point where the two prongs or members project, substantially as described.

2. A metallic fastener, consisting of a at the single point where the two prongs or members project, substantially as described.

3. A metallic fastener, consisting of a duplex-pronged shank having an open loop-head, and a contracted neck in juxtaposition to the loop-head, and a metallic hollow cap applied to the loop-head and internally braced and supported thereby, said cap being elongated through its vertical axis and closed on all sides contracted neck extends, substantially as described. c

4. A metallic fastener, consisting of a hollow metallic cap, elongated through its verticabaxis and a duplex-pronged shank formed integral with a central open loop-head arranged in the plane of the shank and shaped to conform to and fit the internal surface of thehollow metallic cap, substantially as described.

In testimony whereof I have hereunto set my hand in presence of 'two subscribing witnesses.
